Senate Could Stay Up All Night With Financial Reform

Financial reform failed to advance in the Senate for the third straight day Wednesday afternoon, and Sen. Claire McCaskill says Democrats could hold the upper chamber in session through the night, attempting to bring their Wall Street bill to the floor for debate.

"I think we're gonna go all night," McCaskill told MSNBC's Andrea Mitchell in a live interview this afternoon.

"We're talking about staying all night and continually asking our colleagues across the aisle to allow us to debate this bill," the Missouri Democrat said.

Democrats have held votes Monday, Tuesday, and Wednesday seeking to open floor debate on their financial reform bill. Each vote has failed, with Republicans unified in voting "no." Sen. Ben Nelson (D-NE) has joined them.
